Engine Intake Manifold - 1-147-004

The Speedmaster LowRise Manifolds are our lowest profile manifold and is also the only one that is street legal on pollution controlled vehicles. It is set up to accept a spread bore carb but comes with an adapter plate that permits the use of square bore carbs. To remain street legal with a square bore carb, you must use one that is also approved as street legal for your application. This Speedmaster LowRise manifold is designed to fit engine swaps using the 1996 and later Vortec (Gen 1+) cast iron heads or the Edelbrock E-Tec aluminum heads. These cylinder heads are very popular in street rods, engine swaps, or the industrial market. This manifold can be used on any Chevy V-8 engine utilizing the late Vortec head. This manifold has provision for external water bypass.
